Kamole Weir Water Treatment Plant for County of Maui, Hawaii

Using advanced technology to enhance water treatment plant performance

hen M&E was selected by the County of Maui Board of Water Supply to upgrade the Kamole Weir Water Treatment facility, the situation called for an innovative approach.

To comply with the federal Surface Water Treatment Rule (SWTR), as well as the pending Enhanced Surface Water Treatment Rule (ESWTR), the plant was upgraded from direct filtration to microfiltration. Microfiltration is used in wine and juice production but it's relatively new in the U.S. as an application for potable water and wastewater. Essentially, microfiltration is the physical rejection of contaminants through the use of a porous membrane. It operates at lower pressures than other membrane technologies such as ultrafiltration and reverse osmosis.

The scope of the Kamole Weir upgrade, which will provide an average daily flow greater than 6-mgd, includes design of pretreatment and microfiltration facilities; demolition of existing dual media filters; chlorination and drying bed modifications; and influent control. This plant will be on-line by the fall of 1998.
